Understanding the Problem
The upper rack adjuster (adjuster kit) is the plastic assembly at each front corner of the upper rack that rides on the dishwasher's track and sets the rack height/stop. When the adjuster is cracked, worn, or its clip fails the rack can slide unevenly, catch, drop off the track, or fail to lock in the high/low positions. This is a common failure on older dishwashers where the plastic fatigues from repeated use and heat exposure. Replacing the upper rack adjuster kit restores smooth travel and proper stopping of the upper rack. In most cases the repair is straightforward — you remove the upper rack, snap out the broken adjuster and snap in the replacement kit. If the rack track, rollers, or metal mounts are bent or corroded you may need additional parts or minor adjustment to the track for a lasting fix.
Common Symptoms
Upper rack slides roughly or not at all, makes grinding or scraping noises, drops down when pulled, won't lock into place at set heights, or comes off the track.
Common Causes
- Plastic adjuster or clip has cracked or worn from repeated use or heat
- Upper rack roller/wheel worn or broken, causing misalignment
- Track or mounting bracket bent, corroded, or obstructed

Helpful Repair Tip
Pull the upper rack to the front, lift the front slightly and inspect the two plastic adjusters where the rack meets the tub — if you see cracked plastic, missing clips, or a jammed slider the adjuster kit is the culprit. Compare the shape of the broken piece to photos of the replacement kit before ordering.
Frequently Asked Questions
How do I replace the upper rack adjuster kit on my KDPE334GPS0?
General steps: 1) Remove the upper rack by pulling it forward to the stops and lifting the front slightly to disengage the rollers. 2) Locate the damaged adjuster on the front corner(s) of the rack. 3) If equipped with a retaining clip or screw, remove it; otherwise pry the old adjuster out of the rack rail. 4) Snap the new adjuster into place and reattach any clip. 5) Reinstall the rack and test travel. Always disconnect power first and consult manufacturer diagrams for your exact model.
How much does an upper rack adjuster kit cost and can I install it myself?
Parts typically cost between $15 and $60 depending on OEM vs aftermarket. Labor (if you hire a technician) may add $80–$200. The job is usually DIY-friendly for anyone comfortable with basic appliance tasks — it requires no special tools, just a screwdriver or pliers in some designs.
